In fact it started on Thursday with a local owner not taking care of a couple of dogs. I’m not sure about whether or not the dogs are being cared for but there have been a number of cases suggesting that they were thin and also that they were running wild.
Then yesterday it took a turn for the worse shortly after 7am. I was on my way back to the house having fed the horses and then heard an animal calling out. I paused trying to identify this animal. It was located very close to our border on the Northern side.
Then the noise stopped and I thought nothing more of it.Later on I realised that it was animal in serious pain. Too late now to attempt to save it.
A little later I went across to the area where the calling had been coming from. There, just alongside our fence but on the other side of it, lay a young deer. It was dead but still warm.
Then about 10:30 yesterday when after I had called animal control I decided to revisit the location and take a couple of pictures.
oooo
It was tragic! The loss of a wild animal. In fairness, one that the dogs themselves are not responsible for. Dogs will be dogs.
Meantime, I pondered on what might have evolved differently had I intervened when I first heard the animal in pain.

The American people’s relationship with top predators — especially wolves — is complex and ever-evolving. About three decades ago, it was mostly just animal-rights groups and their supporters who fought for the wolves’ right to exist; they were often considered a nuisance. But now there’s plenty of scientific evidence proving what’s good for wolves is good for their prey, the plants those prey eat, and indeed, positively affects the entire ecosystem. That’s ultimately good for humans too — unless you’re competing with the wolves, like a rancher who grazes animals or a hunter who wants to shoot the same deer or moose that wolves need to eat. But at this point, even some ranchers and hunters have come over to the pro-predator side.
Much of that change in the perception of predators is down to studies that have proven how precisely cougars, wolves, bears, tigers, lions, bald eagles, alligators and other apex predators affect the land around them. None have been studied longer than the wolves and moose in Isle Royale National Park, a Guam-sized island in Lake Superior. For almost 60 years, the populations of these two groups have been tracked — as well as their effects on the plants and other animal communities on the island. (You can read the reports here, including the recent 59th annual report.)
As the video above explains, there used to be as many as 50 wolves on Isle Royale; however, that number has dwindled, mostly due to inbreeding that caused a debilitating spinal condition to proliferate among the too-closely-related wolves. Just 10 years ago, there were still around 30 wolves but by 2015, there were only three wolves left. Now, there are just two, a closely related male-female pair that probably won’t breed. (The female of the pair has aggressively fought back when the male attempted to breed with her.)
Already, the moose population on the island has boomed, “undoubtably because of lack of predation,” John Vucetich, a wildlife ecologist from Michigan Technological University told Science magazine, adding that the two remaining wolves are now “… swimming in moose.” Despite the wolves’ regular predation on moose, there’s been a 20 percent increase in moose in just one year, which scientists estimate is about five to 10 times higher than on mainland areas. Beaver populations have also risen sharply. There’s just not enough wolves to keep either population in check.
So what’s so bad about so many moose? Well, as most ungulates do, moose spend their days browsing on vegetation, so the more moose, the more food they need — and the plants on the island can only take so much nibbling. An aquatic plant, which was found in abundance just six years ago, is now only found in places where moose are not. Long-term, this means the island will soon run out of food to keep the ever-larger moose population alive, and many will starve once food becomes scarce. Previously, the wolves have kept moose populations low enough so they didn’t overeat the vegetation, keeping the system in balance.
A plan to rebalance the ecosystem

This is why some people think the best solution is to bring a fresh influx of wolves to Isle Royale National Park. The plan is to release 25-30 wolves over the next three to five years. So far, park officials have trapped four wolves on the mainland beginning in late September and released them on the island. Three of the wolves are female — with the hope they will successfully breed.
This new blood would potentially rebalance the predator-prey relationship and the idea is that the rest of the ecosystem would follow. Introducing so many wolves over several years is hardly natural either, others argue, saying that humans should just be hands off and let nature take its course. The original 50 wolves had found their way to the island on their own, having moved in from Canada; perhaps they could do so again if given the chance.

There is something about a Huskie that takes one’s breath away. Not only because of the grace and wit with which they conduct their lives but also because the majority of them are working dogs.
So it was with interest that I read recently about the Huskies and wanted to share it with you all.

A dog DNA startup company called Embark, based out of Boston, Massachusetts, and Ithaca, New York, appears to have finally solved the mystery as to why huskies sport their beautiful blue eyes. The study is the first consumer genomics study ever conducted in a non-human model, as well as the largest canine genome-wide association study to date, reports Phys.org.
The key, it turns out, lies in the dogs’ 18th chromosome. A duplication on chromosome 18, near the ALX4 gene, was found to be strongly associated with blue eye color. The ALX4 gene plays an important role in mammalian eye development, so this association is not entirely out of left field. And interestingly, the study also found this same genetic quirk in non-merle Australian shepherds, which also tend to have blue eyes.
This flies in the face of how eye color is usually thought to be determined in dogs. For instance, two genetic variants are known to underlie blue eye color in many dogs, but scientists have long known that these variants do not explain the blue eyes of huskies, thus the mystery.
In fact, even though we’re seemingly in a genomic scientific age, the genetic underpinnings of many traits in non-human animals are still largely unknown, even for humans’ best friends. Embark aims to change that.
For the study, which was performed in partnership with Cornell University College of Veterinary Medicine, researchers used a diverse panel of 6,070 genetically tested dogs, with owners who contributed phenotype data — physical traits of the dogs — via web-based surveys and photo uploads. A comprehensive, consumer-driven survey of this size is largely unprecedented.
“Using genetic data from the pets of our customers, combined with eye colors reported by customers for those same animals, we have discovered a genetic duplication that is strongly associated with blue eye color. This study demonstrates the power of the approach that Embark is taking towards improving canine health,” explained Aaron J. Sams of Embark. “In a single year, we collected enough data to conduct the largest canine study of its kind. Embark is currently pursuing similar research projects in a range of morphological and health-related traits and we hope to continue to use our platform to move canine genetics and health forward in a very real way.”
It’s all in the name of improved health care options for our canine companions, as well as helping curious human owners better understand the origins of their pets. Answering why huskies have blue eyes is just the first such mystery they hope to solve.
If you can, please support this PDX event coming up on the 5th.
In my post that was my letter to Mr. Neptune, Colette left a reply that was a ‘heads up’ to an event being held in Portland, Oregon on October 5th. Ergo, this coming Friday.
Now the odds are that very few of you dear readers will be within reach of that event.
But that doesn’t stop me from promoting the event so that the details may be shared as far and wide as possible.
Join us October 5th for a peaceful Demonstration to help endangered Southern Resident Killer Whales. There are only 74 left after the loss of 2 baby Orcas this Summer. You may have seen the dead newborn Orca carried “Save our Orcas”. Meet promptly at Holladay Park at 3:00pm.
ooOOoo
Here’s a news item taken from CBS News.
Then for those that would like more background on the Orca whale, let me republish the opening paragraphs of an item from Wikipedia.
The killer whale or orca (Orcinus orca) is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and dolphins. They have been known to attack baleen whale calves, and even adult whales. Killer whales are apex predators, as no animal preys on them. A cosmopolitan species, they can be found in each of the world’s oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas, absent only from the Baltic and Black seas, and some areas of the Arctic Ocean.
Killer whales are highly social; some populations are composed of matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are often specific to a particular group and passed across generations, have been described as manifestations of animal culture.
Wild killer whales are not considered a threat to humans,[6] but there have been cases of captive orcas killing or injuring their handlers at marine theme parks. Killer whales feature strongly in the mythologies of indigenous cultures, with their reputation ranging from being the souls of humans to merciless killers.

Just the view at night from one small planet, the one that I happen to live on, Planet Earth, reveals millions upon millions of stars. It is then beyond inconceivable that there are not, in turn, countless numbers of other planets.
Extending this line of thought and recognising that a ‘mere’ billion years after the formation of our solar system and Planet Earth, some 4.54 billion years ago, the earliest life appeared, we can’t surely be alone!
Granted it was only cyanobacteria, as in blue-green algae, but, but, but ……… that this evolution of life on Planet Earth, and that evolution eventually leading to intelligent life, including the gift to us humans of the genetic separation of the dog from the wolf some 100,000 years ago, has not occurred on other planets is also totally inconceivable.
So, dear Mr. Cosmos, why have we not detected any signs of that intelligent life. Where are they?
Are we alone in the universe? New Drake equation suggests yes
A fresh take on the decades-old Drake equation incorporates new factors and greater uncertainty, suggesting a high likelihood that humanity is alone in the universe.
At the Los Alamos National Laboratory in 1950, physicist Enrico Fermi famously posed to his colleagues a simple question borne of complex math: ‘Where are they?’
He was asking about aliens—intelligent ones, specifically. The Italian-American scientist was puzzled as to why mankind hasn’t detected any signs of intelligent life beyond our planet. He reasoned that even if life is extremely rare, you’d still expect there to be many alien civilizations given the sheer size of the universe. After all, some estimates indicate that there is one septillion, or 1,000,000,000,000,000,000,000,000, stars in the universe, some of which are surrounded by planets that could probably support life.
So, where are they, and why aren’t they talking to us?
Now, as the article reveals, there is a lot to tackling this question, much of it involving statistics and mathematics, but it does prove one very important fact: Finding another planet as good for life and humanity as this one is just about impossible.
This is our only home!!
My wish, dear Mr. Cosmos, to you is this: That before I die it becomes clear beyond question that the peoples of this sweet Planet, from the lone individual living on some island out in the wilderness to the Governments of the most powerful nations on Earth, understand that nothing is more important than loving, caring for and looking after Planet Earth.
I remain, dear Mr. Cosmos, your respectful servant.
I found it very interesting and wanted to share it with you.

Scientists have been drilling into the ocean floor for 50 years – here’s what they’ve found so far
September 26, 2018

It’s stunning but true that we know more about the surface of the moon than about the Earth’s ocean floor. Much of what we do know has come from scientific ocean drilling – the systematic collection of core samples from the deep seabed. This revolutionary process began 50 years ago, when the drilling vessel Glomar Challenger sailed into the Gulf of Mexico on August 11, 1968 on the first expedition of the federally funded Deep Sea Drilling Project.
I went on my first scientific ocean drilling expedition in 1980, and since then have participated in six more expeditions to locations including the far North Atlantic and Antaractica’s Weddell Sea. In my lab, my students and I work with core samples from these expeditions. Each of these cores, which are cylinders 31 feet long and 3 inches wide, is like a book whose information is waiting to be translated into words. Holding a newly opened core, filled with rocks and sediment from the Earth’s ocean floor, is like opening a rare treasure chest that records the passage of time in Earth’s history.
Over a half-century, scientific ocean drilling has proved the theory of plate tectonics, created the field of paleoceanography and redefined how we view life on Earth by revealing an enormous variety and volume of life in the deep marine biosphere. And much more remains to be learned.
Technological innovations
Two key innovations made it possible for research ships to take core samples from precise locations in the deep oceans. The first, known as dynamic positioning, enables a 471-foot ship to stay fixed in place while drilling and recovering cores, one on top of the next, often in over 12,000 feet of water.
Anchoring isn’t feasible at these depths. Instead, technicians drop a torpedo-shaped instrument called a transponder over the side. A device called a transducer, mounted on the ship’s hull, sends an acoustic signal to the transponder, which replies. Computers on board calculate the distance and angle of this communication. Thrusters on the ship’s hull maneuver the vessel to stay in exactly the same location, countering the forces of currents, wind and waves.
Another challenge arises when drill bits have to be replaced mid-operation. The ocean’s crust is
The re-entry cone is welded together around the drill pipe, then lowered down the pipe to guide reinsertion before changing drill bits. IODP, CC BY-ND
composed of igneous rock that wears bits down long before the desired depth is reached.
When this happens, the drill crew brings the entire drill pipe to the surface, mounts a new drill bit and returns to the same hole. This requires guiding the pipe into a funnel shaped re-entry cone, less than 15 feet wide, placed in the bottom of the ocean at the mouth of the drilling hole. The process, which was first accomplished in 1970, is like lowering a long strand of spaghetti into a quarter-inch-wide funnel at the deep end of an Olympic swimming pool.
Confirming plate tectonics
When scientific ocean drilling began in 1968, the theory of plate tectonics was a subject of active debate. One key idea was that new ocean crust was created at ridges in the seafloor, where oceanic plates moved away from each other and magma from earth’s interior welled up between them. According to this theory, crust should be new material at the crest of ocean ridges, and its age should increase with distance from the crest.

The only way to prove this was by analyzing sediment and rock cores. In the winter of 1968-1969, the Glomar Challenger drilled seven sites in the South Atlantic Ocean to the east and west of the Mid-Atlantic ridge. Both the igneous rocks of the ocean floor and overlying sediments aged in perfect agreement with the predictions, confirming that ocean crust was forming at the ridges and plate tectonics was correct.
Reconstructing earth’s history
The ocean record of Earth’s history is more continuous than geologic formations on land, where erosion and redeposition by wind, water and ice can disrupt the record. In most ocean locations sediment is laid down particle by particle, microfossil by microfossil, and remains in place, eventually succumbing to pressure and turning into rock.
Microfossils (plankton) preserved in sediment are beautiful and informative, even though some
are smaller than the width of a human hair. Like larger plant and animal fossils, scientists can use these delicate structures of calcium and silicon to reconstruct past environments.
The resulting acidification of the ocean from the release of carbon into the atmosphere and ocean caused massive dissolution and change in the deep ocean ecosystem.
This episode is an impressive example of the impact of rapid climate warming. The total amount of carbon released during the PETM is estimated to be about equal to the amount that humans will release if we burn all of Earth’s fossil fuel reserves. Yet, an important difference is that the carbon released by the volcanoes and hydrates was at a much slower rate than we are currently releasing fossil fuel. Thus we can expect even more dramatic climate and ecosystem changes unless we stop emitting carbon.

Today scientists from 23 nations are proposing and conducting research through the International Ocean Discovery Program, which uses scientific ocean drilling to recover data from seafloor sediments and rocks and to monitor environments under the ocean floor. Coring is producing new information about plate tectonics, such as the complexities of ocean crust formation, and the diversity of life in the deep oceans.
This research is expensive, and technologically and intellectually intense. But only by exploring the deep sea can we recover the treasures it holds and better understand its beauty and complexity.

Did the phrase in the first paragraph of the article jump out for you as it did for me?
This one: “…we know more about the surface of the moon than about the Earth’s ocean floor.”
Doesn’t Mr. Neptune hold his cards close to his chest.
Your oceans of the world are truly breath-taking. The power you can display in the odd wave or million through to the tranquility you so often also display defy rational explanations.
I have had the profound experience of sailing upon your waters, dear Mr. Neptune, over a number of years sailing back and forth between Cyprus and Turkey. Not a long distance but still sufficient to experience being solo on a yacht day and night.
Tradewind 33 – Songbird of Kent. My home for five years.
Then on my way sailing back to Plymouth, SW England, the magical, almost primeval, feeling of being alone on the Atlantic Ocean. Looking up at the night sky, feeling so insignificant, so infinitesimally minute with 500 miles of open ocean in all directions and those stars above my head.
No question, that practically everything about your oceans is beyond the understanding of us humans. Indeed, I had to look up online how much water there is on Earth to discover there is:
It’s roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey.
Because I simply didn’t have a clue.
And knowing there are approximately 326 million cubic miles of water doesn’t help because I am still left not having a clue as to what that means!
So, thank goodness, Mr. Neptune this is all a ‘walk in the park’ for you!
But I do have a question for you.
What do you make of this?
The image is cropped from the following:
The description of these figures is:

And it was taken from research undertaken by Lijing Cheng and Jiang Zhu and found on the web here.
Ocean Heat Content
Owing to its large heat capacity, the ocean accumulates the warming derived from human activities; indeed, more than 90% of Earth’s residual heat related to global warming is absorbed by the ocean (IPCC, Cheng et al. 2017). As such, the global ocean heat content record robustly represents the signature of global warming and is impacted less by weather-related noise and climate variability such as El Niño and La Niña events (Cheng et al. 2018). On the other hand, ocean thermal expansion due to ocean temperature change contributes substantially (30%~50%) to the sea level change, which can considerably influence human populations in coastal and island regions and marine ecosystems. Therefore, monitoring the OHC changes and understanding its variation are crucial for climate change.
Is it possible, Mr. Neptune, that even you as the master of all our oceans is worried about the future?
I shall cut my waffling and just say that I saw this item on The Smithsonian ‘Smart News’ section last week and just knew it should be shared with you!

Who’s a Good Archaeologist? Dog Digs Up Trove of Bronze Age Relics
While on a walk outside a small Czech village, Monty the dog and his owner found nearly two dozen 3,000-year-old artifacts

Some archaeologists carry tools and painstakingly chip away at historic sites. Others might have fluffy bodies, keen senses of smell and an affinity for digging stuff up.
As Tom McEnchroe reports for Radio Praha, a very good dog named Monty recently unearthed a rare trove of Bronze Age artifacts near the Czech village of Kostelecké Horky. Monty was walking with his human, identified as “Mr. Frankota,” in a field when he began pawing frenetically at the ground. Soon, thanks to Monty’s hard work, metallic objects began to emerge in the soil.
The cache of relics includes 13 sickles, two spear points, three axes and several bracelets. The objects have been dated to the Urnfield period around 3,000 years ago. This late European Bronze Age culture is marked by the transition from inhumation burials to cremations; the remains of the dead were interred in urns, giving the era its name. According to Encyclopaedia Britannica, Urnfield culture first appeared in east-central Europe and northern Italy, but eventually spread “to Ukraine, Sicily, Scandinavia, and across France to the Iberian peninsula.”
It is rare to find a cluster of intact Urnfield objects, according to a press release. “The culture that lived here at the time normally just buried fragments, often melted as well,” Martina Beková, an archaeologist at the Museum and Gallery of Orlické who studied the artifacts after they were discovered by Monty, tells McEnchroe. So she suspects that the relics were tied to a ritual—“most likely a sacrifice of some sorts,” Beková says.
Additional evidence could help pin down the function of the objects, and according to Michelle Starr of Science Alert, local archaeologists have been searching the area in the hopes of finding more relics. They haven’t uncovered anything yet, but Sylvie Velčovská, a spokeswoman for the region, tells McEnchroe that there have been, “considerable changes to the surrounding terrain over the centuries, so it is possible that the deeper layers are still hiding some secrets.”
The newly uncovered objects will be on display at the Museum and Gallery of Orlické Mountains in the town of Rychnov until October 21, after which point they will undergo conservation and be moved to a permanent exhibition in the village of Kostelec.
Frankota, Monty’s owner, was awarded 7860 Czech Koruna (around $360) for his role in alerting archaeologists to the ancient treasures. One can only hope that Monty was given many treats and pets for his superb fieldwork
